This data set includes 1-minute averages of the electric and
    magnetic wave spectra obtained during the period that the Galileo
    plasma wave receiver was operated during the Jupiter orbital
    mission (prime, GEM and GMM). The parameter provided for the
    electric field spectrum is the electric field spectral density
    in units of V**2/m**2/Hz.  The magnetic field spectrum is
    provided in units of magnetic field spectral density, nT**2/Hz.
    The spectral information is averaged and binned into 49
    logarithmically-spaced channels from about 6 Hz to 5.6 MHz for the
    electric measurements and 34 channels from about 6 Hz to 75 kHz for
    the magnetic.  Note that these 'channels' do not generally
    correspond to the 158 specific channels described in the instrument
    description document.  The reduction in spectral resolution for this
    data set was performed in order to make the set more conducive to
    use as a browse data set.  The sources of this browse data set are
    the High Frequency Receiver, Sweep Frequency Receiver, and Spectrum
    Analyzer which make up the Low Rate Science portion of the PWS.

    This data set is highly discontinuous in time. Because of the severe
    limitations in the downlink capability of the Galileo spacecraft,
    data were acquired for only selected portions of each orbit. During
    the prime mission (first 12 orbits), continuous data were acquired
    inside of 50 Rj for all orbits, with a few select orbits having
    complete or nearly complete coverage in the Real-Time Science (RTS)
    telemetry mode. During most of the Galileo Europa Mission (GEM) and
    Galileo Millennium Mission (GMM) coverage was more limited, typically
    only a few days around perijove, except for the Cassini encounter
    period (orbits 28 and 29) and orbits where recorded data were lost
    due to spacecraft safings or other mishaps. Table 1 below provides
    a listing of the start and stop times of the data for each orbit.
    Some orbits (5 and 13) have no coverage due to solar conjunctions.
    Table 2 below provides basic information about the orbits and
    orbital geometry. After the insertion orbit, which dipped as low as
    five degrees south, the Galileo remained within a degree of the
    jovian equator.

        * Solar conjunction - no data from this orbit
        ** Rj = 71492 km

This data set includes all available Low Rate Science spectrum
    analyzer data within the interval of time covered. The data included
    in this set are the real time data stream which have been edited and
    compressed using an integer cosine transform.  Amplitude inaccuracy
    of the order of 5 dB is expected due to the lossy nature of the
    compression algorithm.  The magnetic spectra contain narrowband
    interference lines at 2.4 kHz and harmonics.  Occasionally, magnetic
    noise between about 200 Hz and 2 kHz due to UVS grating motor
    activity can be observed.  Periodic bursts of noise below about 100
    Hz are due to the stepper motor on the Energetic Particle Detector.
    Missing data are indicated by zero.

    At about 1712 SCET on 14 September (day 257) 1997 the low-frequency
    search coil, or some portion of the PWS electronics associated with
    the signals acquired by this sensor suffered a failure which
    increased the noise level and decreased the sensitivity for magnetic
    signals below 2.4 kHz. Some natural signals can be observed in this
    frequency range after the failure, but no attempt has been made as
    of this date to recalibrate the output of this sensor.  After some
    on-board testing of the affected systems it was decided to only use
    the search coils inside of about 15 RJ for the duration of the
    mission.  Inside this distance, it is most likely that intense
    electromagnetic signatures might still be detected in the anomalous
    sensor state.  Outside of about 15 RJ, the instrument will be
    commanded into an electric field-only mode.

    In the electric field-only mode, every 18.67-second sweep of the
    spectrum analyzer and medium frequency receiver is from the electric
    dipole antenna, effectively improving the temporal resolution of the
    electric field measurements below 100 kHz by a factor of two.  The
    high frequency receiver above 100 kHz also sweeps once per 18.67
    seconds, only on the electric antenna.
